0.9.1.0: Some UI improvements

This is just a small update which has various UI improvements and a fix to error reporting.

UI -Stockpiles and trade storage can now have a limited amount of goods specified with a slider in the stockpile window (see image below). This is useful when you want to trade only some part of your food or materials. The slider also has an 'unlimited' setting, which is the default. -Tools now have a list of all the objects/processes that they can be used for (with a maximum cap). -Some HUD windows such as gather, stockpile, hunt are now resizable. -All HUD (green pop-up) windows are now movable.

Other -In the Task Manager panel, made some adjustments to the priority groups 'Sowing/Harvesting', 'Weeding/Fertilizing' and 'Check Traps'. -Made a fix so that more crashes can be presented to the player as a dialog instead of only appearing in the Windows log.
